At present, vacuum dryer be widely used in the industries such as pharmacy, food, chemical industry, paper products dry materials, heat, sterilization and slaking aspect.When most of vacuum dryers move, at first by power generator generation thermal source, through energy feed system energy input is transferred in the vacuum chamber, material is delivered to by transport sector and absorbs the energy in the vacuum chamber, the evaporation that heats up under the effect of the energy of the moisture content in material this moment, the most of moisture content and the moisture that are evaporated are extracted out by vacuum lead.Small amount of moisture contact cavity inner wall is arranged, because cavity internal-external temperature difference relation, moisture can be become the globule is dropped on the dry material or trickles at the bottom of the jar, have a strong impact on the rate of drying and the quality of material, the waste microwave energy, and make monitoring device on the cavity can't accurately monitor ruuning situation in the chamber.Once researched and developed a kind of energy saver of vacuum dryer at this technical problem the applicant, and on March 17th, 2006 application china national practical new-type patent (application number is: 200620078620.8), the vacuum dryer energy saver that above-mentioned patent application provides, nadir in cavity is established water storage and jettison gear, this device has just solved jar emission problem of inner bottom part condensed water, but the problem that easily is dropped on the dry material for the condensed water at cavity top is still unresolved.

Summary of the invention

The purpose of this utility model is a kind of loss that can avoid unnecessary microwave energy, and can improve material rate of drying, guarantee the de-watering apparatus of micro-wave vacuum equipment of the drying quality of material.

For achieving the above object, the technical scheme that the utility model is taked is: a kind of de-watering apparatus of micro-wave vacuum equipment is characterized in that being provided with heater on the top or the top of vacuum tank tank body.

Above-mentioned heater is by the interlayer that is arranged on vacuum tank tank body top or centers on the sealing heat circulating system that thermal medium constitutes jointly in the interlayer of tank body integral body, the heating tube in the interlayer, the turnover pipe that connects heating tube and heat exchanger and the pipe.

Above-mentioned heater is the sealing heat circulating system that is made of jointly interlayer that is arranged on vacuum tank tank body top or the thermal medium in the interlayer of tank body integral body, the turnover pipe that connects interlayer and heat exchanger and interlayer, turnover pipe.

Above-mentioned heater is electric heating tube, electrical heating wire or the infrared heater that is arranged on vacuum tank tank body top or centers on tank body.

The above-mentioned micro-wave vacuum equipment de-watering apparatus that the utility model provides, utilize heater that the tank body top is heated, make its temperature be higher than jar interior temperature or the equality of temperature residual moisture content that evaporates, condenses, make the condensed water in the vacuum dryer cavity evaporate through heater, avoid condensing drip to drop on the dry material, guarantee the drying quality of material, effectively avoid the loss of the unnecessary microwave energy that condensed water causes in the equipment cavity, and can improve the rate of drying of material.Characteristics such as simple in structure, compact, easy control that this de-watering apparatus also has.
